    Best Uses

      Comments about Audio-Technica ATR2100-USB Cardioid Dynamic USB/XLR Microphone:


      - Microphone has 3.5mm jack allowing you to monitor with 0 latency - great function

      - Design is sleek, simple and made of metal, feels heavy and of quality

      - Sound quality is great, the range may not be that wide (50-15 000 Hz) but is ample at an amateur / hobby level

      - Overall great value, comes with a stand, zero latency is great function, price is good.


      - Some cheapo carrying pouch / case would have been nice

      - Have heard of quality issues with the USB / Headphone jack such as breaking. Could be resolved if you minimise the number of unnecessary insertion / removal of USB / headphone cable

      Good for:

      - Amateur / hobby singers recording covers

      - Podcaster / Youtube / Voice over

      - Value for money

      - Upgrade from cheapo PC mic / inbuilt microphones

      • Q:

        I am using this mic plugged into a Mac using Garageband. When I have headphones plugged into the mic, and the mic plugged into the Mac via USB, I can barely hear my voice in the headphones. The volume is turned all the way up in the mic and on the Mac.

        Is there another way to increase the volume in the headphones? My headphones do not have any other volume controls.

        Also is there any way of 4 USB mics to go into the Mac and have everyone hear everyone at once if they have headphones?

      • Q:

        The recording level is very low... how do I fix this?

        I use 4 ATR 2100 USB mics connected via XLR to a FCA1616. When recording, the levels are very low and if I turn up the gain on the interface to compensate, the hiss is extremely loud. I have tried several different interfaces/mixers and the problem persists.

        • A:

          Make certain that your microphone cables are XLR female to XLR male type cables, so you are connecting the mics to the MIC level XLR section of the XLR /1/4" combo jacks on your interface. The level WILL be very low if you are using XLR female to 1/4" male type cables and connecting the mics to the 1/4" LINE level section of the combo jacks. This is because the 1/4" section of the jack is expecting a LINE level signal coming into it. A microphone signal is considerably lower in level.
          If you are using XLR to XLR type cables and the level is still low, move the microphone closer to the sound source, increase the level of the sound source or both.

        The light on my ATR2100 doesn't turn on anymore.

        The light on my mic doesn't turn on anymore and I have noticed that the sound isn't the same when I record on my Mac. Does that mean something is broken on the inside of the mic? Is there something I can do to fix it?

        Can I get the ATR2100-USB Cardioid Dynamic USB/XLR Microphone in New Zealand or Japan?


        I'm currently in New Zealand and can't find the ATR2100-USB Cardioid Dynamic USB/XLR Microphone anywhere! Is it even available here?

        I'll be in Japan in a couple of months (Tokyo, Kyoto and Osaka), so is it available anywhere there? I can't seem to find it anywhere by searching online.

      • Q:

        Cardiodi dynamic usb/xlr mic won't output on Mac

        I purchased this microphone so that my daughter can sing at home. I just want it to output when connected to the Mac computer. I don't plan to record.
        I set up the mic like the manual guided me to. It recognizes the mic but it won't output sound. I've made sure my output it through the computer speakers but still nothing.

        Please advise on how to make this work.

      • Q:

        Is my Audio-Technica ATR2100 usb compatible with a video camera?

        I have an HDR video camera with a 3.5 mm jack. I purchased an adapter (usb to 3.5 mm jack). I connected the ATR2100 to the video camera and it did not work well.

        My camera automatically recognized the microphone but ... the blue light did not come on the microphone. The result was static every time I tested it.

        • A:

          There are 3.5 mm to USB adapters (from source to detination), but I am not aware of USB to 3.5 mm adapters. Such an adapter would have to change the signal from a digital (USB) type signal to an analog (3.5 mm) type signal, and it would have to supply 5 volts DC bus power to the microphone. It is more feasible to go from the XLR output connector on the microphone to the 3.5 mm Microphone jack on a camera. This type jack today is typically a STEREO jack. With the appropritate XLR to 3.5 mm adapter cable you can get microphone audio (which is mono) on both the left and right sides of a stereo jack. Following is a link to such a cable.

      • Q:

        Is ATR2100 affected by phantom power when mic is turned off?

        My mixer supplies phantom power to all inputs when phantom power is turned on. If I have an ATR2100 and ATR2005 plugged into the mixer while phantom power is on, BUT THE MICROPHONES ARE NOT TURNED ON, will this be OK?

        I would NOT turn the microphones on until phantom power is turned off. However, I don't know if I would be damaging the microphones even if they are turned off while phantom power is on.

        1 answer

        • A:

          The ATR2100USB and AT2005USB are dynamic microphones, so Phantom Power should not effect them. HOWEVER, it is best to leave phantom power turned off if it is not being used.
